Application filed October 1, 1917. Serial-No. 194,185.

To all it may concern:

Be it known that I, Evnnn'rr M HAWL'EY,

a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Valves for Gas Ranges, of which the following is a specification.

My invention relates to certain improvements in gas stoves or ranges having an oven in which there are two burners or two sets of burners, one arranged .to be used for broiling and the other for baking.

' One object of the invention is to provide a single valve for'controlling the flow of :gas to the two burners, so thatv the supply of gas toone burner must be cut ofi beforethe gas can be supplied to the other burner;

Another object of the invention is to provide a valve so that both burners'can be cut oil", or either burner.

Still another object of the invention is to provide an indicator and movable stop for,

the valve handle when the gas is shut 01f.

In the accompanying drawing "Fig. 1, is a sideview of m valve for regulating the flow 0 gas to two burners or two sets of burners;

Fig. 2, is an end view ofthe device illustratpd in Fig. 1;

Fig. 3,. is a sectional view on the line. 3-3, Fig. 2; and Fig. 4, is a'view of a portion of-a gas range, showing the oven and the location of the valve burners 1 is the body of a range. 2 is the oven. 3 is a pipe leading to the broiling burners in the upper portlon of the oven. 4' is a and the pipes leading to the pipe leading to the baking burners in the ower portion ofthe oven. 5 is a gas sup ply pipe and 6 is the casing of my improved valve located at the junction of the pipes 3 and "4 with the supply pipe 5. The several p'pes are screwed into the valve casing 6 in the .ordinary manner.

-.In the valvecasing is a three-way valve 7 having ports so arranged that the supply of gas will be cut oil from the main pipe 5 to both pipes 3 and 4. The valve can be turned so as to allow the gas supply pipe 5 to comimproved municate with the pipe 3 leading to the brollmg burners, cuttmg off the baking burners, or can be turned to allow communication between the'supply pipe 5 and the pipe leading to the baking oven, cutting off the broiling burners. 13 is an ordinary stop pin carried by the valve 7 and arranged to come in contact with stops 14 and 15 to limit the movement of the valve. This arrangement is common in as valves.

The-valve 7 has a hand e8 and on the.

face oil the valve is a dial 9 secured by screws 10 to the casin 6 of the valve. Project ng through the gial is a stop 11, held prO e'cted by a flat spring 12, in'the present instance mounted on one of the screws 10.

When the handle 8 is in the position shown in Fi 1,'then both the pipes .3 and 4 are cut 0 from the suppl ipe 5 and the valve handle may be turned own so as to allow the gas to pass from the supply pipe 5 through the pipe 4 to the baking burners in the'bottom of the oven and the pipe? is cut oil, the pin coming in contact with the stolp 14 fit be desired to use the broiling burners,

then the pin 11 is depressed so as to allow with the two valves and locking mecha-- nism' between the two valves, which is necessary to properly. safeguard the user. The

valve can be placed at any point on the range, according to the particular location of the several pipes.

It'is the usual practice to locate two and sometimes four burners above and below the oven, but it will be understood that my invention can be used for regulating the flow of gas to a single burner at each point, or to a set of burners at said points.

I claim The combination in a gas stove, or range,

cured t0 the dial and so located as to prevent the movement of the handle from beyond the cut-off position without first de- 10 pressing the pin.

In witness whereof I afiix my signature.

. EVERETT M. HAWLEY.
